Title: Switching circuits
IPC: H03K17/74
Filed: 1965-09-28
Abstract: 1,127,031. Selective signalling. NORTH ATLANTIC INDUSTRIES Inc. 28 Sept., 1965 [25 Feb., 1965], No. 41197/65. Heading G4H. [Also in Division H3] Digital-to-analogue converting and digital measuring systems have switching operations performed by a diode bridge with a signal source and load across one diagonal and a controlled biasing source across the other diagonal with one terminal connected to a terminal of the first diagonal (see Division H3). In a digital to-analogue converter (Fig. 5, not shown) the digital signals control a number of such switching bridges which join a summing amplifier to one of a number of taps of a transformer secondary winding via series resistors. The transformer primary is energized by a constant voltage and the tap positions or the series resistors are weighted according to the binary code. In a measuring system (Fig. 6) an input voltage is resolved in unit DC 61  into sine and cosine terms which are applied to transformers T60 and T70 in either phase depending on which switching bridges S 60  or S 61  and S 70  or S 71  is conducting. Each transformer has two secondary windings with taps connected to a series of switching bridges SC 61 , SC 62 , SC 71 , SC 72  which thus form a digital potential divider (details in Fig. 3, not shown) multiplying the input by a controllable fraction depending on which bridge in each set is conducting. The settings of bridges SC 62  and SC 72  are offset from those of bridges SC 61  and SC 71  by a small amount # so that the outputs may be represented as R 1  cos # sin α, R 1  cos # sin (α+#), R 1  sin # cos α and R 1  sin # cos (α+#), where the terms in # refer to the initial resolution and the terms in α represent the controllable multiplying fraction; # is typically 10 degrees. The form outputs are subtracted in the primary and secondary windings of transformers T65 and T75 and fed to a digital-to-analogue converter of the type of Fig. 5. The output of this is compared in a null detector with the reversed voltage from the secondary of transformer T75, and if it is not zero the settings of the various switching bridges in the unit are altered automatically or manually to produce a null output. The adjusting means then indicates the desired value.

Title: Mould-forming and centrifugal metal-casting machine and process
IPC: A61C5/80
Filed: 1963-10-18
Abstract: 983,782. Centrifugal casting. L'ELETTROMETALLURGICA S.p.A. Oct. 18, 1963 [Oct. 20, 1962; Sept. 25, 1963], No. 41216/63. Heading B3F. In a mould forming and centrifugal casting operation a horizontal tubular container 1 rotatably mounted in bearings 4 has a pattern 7 located coaxially therein by fluid pressure means 37 and is supported between arms 10 and 13 and freely rotatable thereon. Moulding sand is introduced under pressure into the container via slits 10a. The container is then rotated and at the same time the pattern is reciprocated transversely to the container axis by movement imparted to the arms 10, 13. A mould cavity is thus formed under the rolling action of the pattern and the sand is compacted. When this action is completed the pattern is centralized in the container and coaxially withdrawn. A lever 17 carrying a ladle 16 swings about a pivot 18 into position to pour a predetermined quantity into one end of the rotating container and mould cavity. The position movement of the lever 17 actuates, in co-operation with a spring-biased rod 20, a lid 23 which closes the other end of the container during the pouring operation. At the completion of the casting operation the lever 17 and ladle 16 move away and another pivotable arm 27 swings into position coaxial with the mould container 1, and an extractor disc 24 operated by fluid pressure means 26 pushes the completed casting and mould axially out of the container 1.

In an apparatus for inducing sleep or promoting relaxation, four lamps with suitably timed masking screens are arranged to give an optical indication of the four stages of respiration: inhalation, pause, exhalation, pause. The equipment is housed in a case 1 having a front panel 3 and the latter has four slit-like windows 11, 12, 13, 14 behind which the lamps are arranged. The masks are part-cylindrical and each rotates around its associated lamp so that a light first appears at the bottom of the window 11 and gradually extends upwards over the whole window and is followed by a similar progression along the window 12. When the far end is reached these two lamps are extinguished and the remaining two are illuminated and the masks progressively cut-off the light from the top of window 13 downwards and then from right to left of the window 14. The screens are driven through gearing by a constant speed motor and any one of a number of optional gear ratios may be selected by pushbuttons 41a . . . 46a. A starting button 80 is also located on the remote control unit 6 and the panel 3 also carries a timing switch 7 and a flashing, coloured lamp 8. A uniform rate of travel of the light along the window is achieved by moving the lamps by a cam arrangement.
